Radio frequencies above 100 GHz (e.g., sub-THz) are promising candidates for future communication systems to provide multi-Gbps average data rates, rapid streaming (e.g., the peak data rate on the order of Tbps) with extremely low latency (e.g., less than 1 ms), fiber-like fronthaul and backhaul in rural areas for fiber replacement and edge data centers replacements [1]}, [2]}, [3]}, [4]}. Spectrum regulators (e.g., Japanese MIAC, European CEPT, and FCC in the US) have instituted their views and provisions on frequencies above 100 GHz during the past few years, and possible coexistence and spectrum sharing techniques above 100 GHz are presented in [5]}, [6]}.
